Knowledge is limited on mortality of grand multiparous women (> or =5 deliveries), whose hormonal, metabolic, and social conditions differ from the average. The authors studied overall and cause-specific mortality in 1974-2001 among 87,922 grand multiparous women including 3,678 grand grand multiparous women (> or =10 deliveries) in Finland. Standardized mortality ratios were defined as ratios ...

If a polychromatic ray segment enters an optical system, is dispersed into many slightly different paths through the system, and finally emerges at a single point, then the incident segment defines what Le Grand and Ivanoff called an achromatic axis of the system. Although their ideas of some 65 years ago have inspired important work on the optics of the eye there has been no analysis of such a...

The object of the present paper is to study three-dimensional Lorentzian -Sasakian manifolds which are Ricci-semisymmetry, locally symmetric and have -parallel Ricci tensor. An example of a three-dimensional Lorentzian -Sasakian manifold is given which verifies all the Theorems.

This paper presents a framework for the implementation of online programming competitions, including a set of principles for the design of the multiplayer game and a practical framework for the construction of the competition environment. The paper presents a successful example competition, the 2016-17 Halite challenge, and briefly mentions a second competition, the Halite II challenge, which l...
